Frequently Asked Questions
What is the on-resistance of the PSN3257QPWRQ1?
The PSN3257QPWRQ1 has a maximum on-state resistance (Ron) of 5 Ω, with a channel-to-channel resistance match of 0.07 Ω nominal. These low resistance values ensure minimal signal attenuation and excellent matching between channels in precision analog applications.
What logic voltage level does the PSN3257QPWRQ1 use for control?
The PSN3257QPWRQ1 uses 1.8V logic for its control inputs, enabling direct interfacing with modern low-voltage microcontrollers, FPGAs, and SoCs without level-shifting circuitry, simplifying system design in low-power applications.
How many channels does the PSN3257QPWRQ1 have and what is its switch topology?
The PSN3257QPWRQ1 features 4 independent channels, each configured as a 2:1 SPDT (Single Pole Double Throw) switch. This allows four separate analog signals to each be routed to one of two outputs, providing maximum flexibility in signal multiplexing applications.
What is the off-state isolation of the PSN3257QPWRQ1?
The PSN3257QPWRQ1 provides 75 dB nominal off-state isolation, effectively blocking signal leakage from unselected channels. This high isolation level is critical for audio switching, RF signal routing, and sensor multiplexing applications where crosstalk must be minimized.
